During a September 10 interview on MSBNC Shannon Watts–founder of Moms Demand Action for Gun Sense in America–described her group as a “tsunami of angry of moms” determined to force Congress to “close the private sale loophole” to save lives.

Watts stressed that her group “knows” ending private gun sales by expanding background checks to all sales “will save lives, but Congress does nothing.”

Watts then referenced the August 26 “murder” of Alison Parker in Virginia and talked of how proud her group is to stand beside Andy Parker as he joins a push for gun control that revolves around more background checks. Watts said, “We know [background check laws] work” and “if this Congress won’t do the right thing, [Moms Demand] will get one that will.”

Amid her attacks on private gun sales, references to Alison’s murder, and claims that background checks work, Watts omitted this key information–Alison’s murderer did not buy his gun privately, but from a retailer, and he passed a background check to acquire the handgun.

Yet Watts contends that private gun sales are the problem and says her group of moms “are not going away.” In fact, she described women in her group as a bunch of gun control proponents who intend to keep nagging “like drips on a rock” until Congress finally caves.
